Adds various useful things to the repl inspired by ipynb and the julia
vscode extension which can be best seen with this video:

To summarize:
## Inline outputs
Added small, single-line outputs displayed inline at the end of the code
line instead of in a separate block. This provides a cleaner, more
compact view for simple results like numbers or short strings. This
occurs for execution views who only output a single mimetype/plain OR
output nothing, otherwise the default behavior of creating a block will
occur.
It looks like this:

/>
This was inspired by julia vscode extension, but now it can be used with
any replanguage! Hooray!

It saves lots of space compared to the ugly and distracting:

/>
## Gutters and execution numbers
Added gutters + execution number to display exactly what was executed.
The gutter highlighting is useful for when selecting multiple cells
manually to run, but you dont remember which ones
Ran at different times:

src="https://github.com/user-attachments/assets/2690ea35-2bd3-4207-b039-6c0f98dad6e4"
/>
The execution number is useful in the same way that a normal jupyter
notebook execution number is useful.
If a gutter-region does not have a block assigned to it, when you edit
the text in the gutter region, the gutter will disappear, which is
useful for telling when you have modified your code, but does not delete
useful experiment results in blocks:

/>
## Skip empty line
This is a minor fix which is intended to make lab workflow less tedious.
Currently when you execute on an empty line (which might be there for
formatting purposes) nothing will occur. This PR adds the ability to,
when executing from an empty line, skip ahead the range of inclusion
until you reach actual code, and then execute.
Before:
```
code //run execute
//empty space, so you have to move your cursor down or use arrow key
code //run execute
code //run execute
```
After:
```
code //run execute
//empty space, you can now run execute on it and it will include the next line of code
//empty space
code //automatically executed
code //run execute
```
Currently the only piece of tested code is related to this, i still have
to write tests for the gutter annotation api i added and all of the
gutter + inline related code. Also still have to add more config for
this stuff.
@rgbkrk would appreciate a review :D
Closes#22678
Release Notes:
- repl: Added an inline display of execution results (as opposed to the
large execution view) for simple REPL cells
- repl: Improved how execution of empty lines are handled
- repl: Added gutter execution display
in release mode: found many log error as `ERROR [rope::chunk] byte index
48 is not a char boundary; it is inside '，' (bytes 46..49)`
This is easy testing,
- enable signature help

Holding control while dragging text to copy it was being blocked by link
handling stopping the propogation of the mouse event; solution: don't
handle link clicks when selection_drag_state is Dragging.
Issue found & fix tested on Linux (since the modifier key on mac is
apparently different, the issue likely doesn't occur there, but I'm
assuming it does apply to Windows).
I didn't see an issue open for it, and since I fixed it myself I'm
unsure whether it needs one or if the PR is enough.
Release Notes:
- Fix an issue where Ctrl+drag to duplicate selected text on Linux and
Windows when the selection is inside a link.
Breadcrumb visual reorchestration which makes a couple of key changes:
- Breadcrumbs are now displayed in file headers for multibuffer views.
Singleton buffers are unchanged.
- Multibuffer views now have collapse/expand all buttons available in
the toolbar
- Search in multibuffer views now takes up less space, by occupying the
primary toolbar location erstwhile taken up by breadcrumbs

We use `block_with_timeout` to give the reparse task a millisecond to
complete, and if it takes longer we put the work off to the background.
The reason for this is that we want tree-sitter based features to feel
snappy.
The reparse task is non-cooperative though, it has no yield points,
giving us no place to actually check for our timeout, meaning we will
always drive it to completion and block for the entire duration.
This kicks out the `block_with_timeout` in favor of using the treesitter
progress callback to handle timeouts instead.
Release Notes:
- Improved responsiveness with very language language files on edits
When adding selections above/below with `skip_soft_wrap: true`, use
buffer column positions instead of pixel positions. This ensures
selections are placed at the same column offset in the buffer rather
than at the same visual position, which was incorrect for soft-wrapped
lines.
For example, selecting "how" in a wrapped line:
````
1. Very long line to
show [how] a wrapped
line would look
2. Very long line to
show how a wrapped
line would look
````
Now correctly adds a selection at the same buffer column in the next
line:
````
1. Very long line to
show [how] a wrapped
line would look
2. Very long line to
show [how] a wrapped
line would look
````
Closes#42137
Release Notes:
- Improved `editor: add selection above` and `editor: add selection
below` to select at the same text column when skipping soft-wrapped
lines, instead of the same visual position
Closes#45046
The root of the issue is anchor resolution. When we apply adjacent
edits, they get merged into a single edit. In the scenario described in
the issue, this is what happens:
1. We create an anchor at the end of each selection (bias::right) on the
snapshot before the edits.
2. We collect the edits and apply them to the buffer.
3. Since the edits are adjacent (>=), the buffer merges them into a
single edit.
4. As a result, we apply one edit to the text buffer, creating a single
visible fragment with length = 3.
5. The buffer ends up with fragments like: [F(len = 3, visible = true),
F(len = 1, visible = false), ...]
6. After the edits, we resolve the previously created anchors to produce
zero-width selections (cursors).
7. All anchors resolve into deleted fragments, so their resolved offset
equals the cumulative visible offset, which is 3.
8. We now have 3 cursors with identical coordinates (0;3).
9. These cursors get merged into a single cursor.
I tried several approaches, but they either felt wrong or didn’t work.
In particular, I tried adjusting anchor resolution using the delta
stored in handle_input, but this doesn’t help because selections are
merged immediately after anchor resolution.
The only workable solution I found is to avoid anchors entirely for the
adjacent-edit case. Instead, we can compute the final cursor positions
directly from the edits and create the selections based on that
information.
Release Notes:
- Fixed an issue where adjacent selection insert would merge cursors

This mimics VSCode's `files.readonlyExclude` setting, to allow setting
specific path matches as readonly locations like lockfiles and generated
sources etc.
Also renders a lock icon to the right side of the path names for
readonly files now.
This does a couple more things for completion sake:
- Tabs of readonly buffers now render a file lock icon
- Multibuffer buffer headers now render a file lock icon if the excerpts
buffer is readonly
- ReadWrite multibuffers now no longer allow edits to read only buffers
contained within
Release Notes:
- Added `read_only_files` setting to allow specifying glob patterns of
files that should not be editable by default

## Summary
Fixes#44812
The hover highlight for clickable inlay hints was not covering the last
character when the label contained multi-byte UTF-8 characters (e.g.,
`→`).
## Problem
When hovering over an inlay hint like `→ app/Livewire/UserProfile.php`,
the highlight/underline stopped one character short, leaving the final
character unhighlighted.
**Root cause:** `find_hovered_hint_part()` in `hover_popover.rs` used
`part.value.chars().count()` (character count) but `InlayOffset` wraps
`MultiBufferOffset(pub usize)` which is byte-based.
For a label like `→ app/Livewire/UserProfile.php`:
- Byte length: 32 (the `→` character is 3 bytes in UTF-8)
- Character count: 30
This mismatch caused the calculated highlight range to end 2 bytes
short.
## Changes
1. **Use byte length instead of character count** (line 112):
```rust
// Before (buggy)
let part_len = part.value.chars().count();
// After (correct)
let part_len = part.value.len();
```
2. **Fix boundary condition** (line 113): Changed `>` to `>=` for
correct `[start, end)` range semantics when hovering at part boundaries.
3. **Rename variable** for clarity: `hovered_character` →
`offset_in_hint` since it's a byte offset, not a character position.
4. **Add unit test** reproducing the exact scenario from the issue with
multi-byte UTF-8 characters.
## Testing
Added `test_find_hovered_hint_part_with_multibyte_characters` which:
- Verifies the label `→ app/Livewire/UserProfile.php` has 32 bytes but
30 characters
- Tests hovering at the last byte correctly returns the full range
- Tests boundary behavior with multiple label parts containing
multi-byte characters
Release Notes:
- Fixed inlay hint hover highlight not covering the last character when
the label contains multi-byte UTF-8 characters

The minimap usually renders about 10x more lines of code and shaped text
than the editor. With expensive fonts such as Google Sans Code, this can
cause noticeable lag, since we attempt to synthesize 300+ lines of code
using a heavy font. Because minimap text is rendered at around 2px and
is essentially illegible, it doesn’t make sense to use the custom buffer
font.
Release Notes:
- Improved minimap performance when using custom fonts

Closes#45960
Release Notes:
- Made the `extension` key context case-insensitive. This e.g. enables
the `markdown: Open Preview` action to also handle files where the
extension is capitalised as MD (case-sensitive file system).
This PR reworks the (still feature-gated) side-by-side diff view to use
a different approach to representing the multibuffers on the left- and
right-hand sides.
Previously, these two multibuffers used identical sets of buffers and
excerpts, and were made to behave differently by adding a new knob to
the multibuffer controlling how diffs are displayed. Specifically, the
left-hand side multibuffer would filter out the added range of each hunk
from the excerpts using a new `FilteredInsertedHunk` diff transform, and
the right-hand side would simply not show the deleted sides of expanded
hunks. This approach has some problems:
- Line numbers, and actions that navigate by line number, behaved
incorrectly for the left-hand side.
- Syntax highlighting and other features that use the buffer syntax tree
also behaved incorrectly for the left-hand side.
In this PR, we've switched to using independent buffers to build the
left-hand side. These buffers are constructed using the base texts for
the corresponding diffs, and their lifecycle is managed by `BufferDiff`.
The red "deleted" regions on the left-hand side are represented by
`BufferContent` diff transforms, not `DeletedHunk` transforms. This
means each excerpt on the left represents a contiguous slice of a single
buffer, which fixes the above issues by construction.
The tradeoff with this new approach is that we now have to manually
synchronize excerpt ranges from the right side to the left, which we do
using `BufferDiffSnapshot::row_to_base_text_row`.

There were several places adding a copy icon button, so thought of

## Open Questions(Would be nice to get some advice here)
- Binary Fetching:
- I'm pretty sure the binary fetching is suboptimal. The main problem
here was getting access to the delegate but i figured that out
eventually in a way that i _hope_ should be fine.
- The toolchain and binary options can differ from what the user has
configured potentially leading to mismatches in the autocomplete values
returned(these are probably rarely changed though). I could not really
find a way to fetch these in this context so the provided ones are for
now just `default` values.
- For the trait API it is just provided a binary, since i wanted to use
the potentially cached binary from the CachedLspAdapter. Is that fine
our should the arguments be passed to the LspAdapter such that it can
potentially download the LSP?
- As for those LSPs with JSON schema files in their repositories i can
add the files to zed manually e.g. in
languages/language/initialization_options_schema.json, which could cause
mismatches with the actual binary. Is there a preferred approach for Zed
here also with regards to updating them?
Closes https://github.com/zed-industries/zed/issues/43208
This PR essentially unblocks the editable number field. The function
that shapes editor lines was hard-coding text alignment to the left,
meaning that whatever different alignment we'd pass through
`EditorStyles`would be ignored. To solve this, I just added a text align
and align width fields to the line paint function and updated all call
sites keeping the default configuration. Had to also add an
`alignment_offset()` helper to make sure the cursor positioning, the
selection background element, and the click-to-focus functionality were
kept in-sync with the non-left aligned editor.
Then... the big star of the show here is being able to add the `mode`
method to the number field, which uses `TextAlign::Center`, thus making
it work as we designed it to work.
https://github.com/user-attachments/assets/3539c976-d7bf-4d94-8188-a14328f94fbf
Next up, is turning the number filed to edit mode where applicable.
Release Notes:
- Fixed a bug where different text alignment configurations (i.e.,
center and right-aligned) wouldn't take effect in editors.
The failure would happen if the current version of the file was open as
an editor. This happened because the git blob and current version of the
buffer would have the same `ProjectPath`.
The fix was adding a new `DiskState::Historic` variant to represent
buffers that are past versions of a file (usually a snapshot from
version control). Historic buffers don't return a `ProjectPath` because
the file isn't real, thus there isn't and shouldn't be a `ProjectPath`
to it. (At least with the current way we represent a project path)
I also change the display name to use the local OS's path style instead
of being hardcoded to Posix, and cleaned up some code too.

This PR is an additive change introducing the `truncate_start` method to
labels, which gives us the ability to add an ellipsis at the beginning
of the text as opposed to the regular `truncate`. This will be generally
used for truncating file paths, where the end is typically more relevant
than the beginning, but given it's a general method, there's the
possibility to be used anywhere else, too.

This PR introduces support for Next Edit Suggestions while doing away
with calling legacy endpoints. In the process we've also removed support
for cycling completions, as NES will give us a single prediction, for
the most part.
Closes#30124
Release Notes:
- Zed now supports Copilot's [Next Edit
Suggestions](https://code.visualstudio.com/blogs/2025/02/12/next-edit-suggestions).
## Summary
Addresses #16965
This PR adds support for **opening and saving** files with legacy
encodings (non-UTF-8).
Previously, Zed failed to open files encoded in Shift-JIS, EUC-JP, Big5,
etc., displaying a "Could not open file" error screen. This PR
implements automatic encoding detection upon opening and ensures the
original encoding is preserved when saving.
## Implementation Details
1. **Worktree (Loading)**:
* Updated `load_file` to use `chardetng` for automatic encoding
detection.
* Files are decoded to UTF-8 internal strings for editing, while
preserving the detected `Encoding` metadata.
2. **Language / Buffer**:
* Added an `encoding` field to the `Buffer` struct to store the detected
encoding.
3. **Worktree (Saving)**:
* Updated `write_file` to accept the stored encoding.
* **Performance Optimization**:
* **UTF-8 Path**: Uses the existing optimized `fs.save` (streaming
chunks directly from Rope), ensuring no performance regression for the
vast majority of files.
* **Legacy Encoding Path**: Implemented a fallback that converts the
Rope to a contiguous `String/Bytes` in memory, re-encodes it to the
target format (e.g., Shift-JIS), and writes it to disk.
* *Note*: This fallback involves memory allocation, but it is necessary
to support legacy encodings without refactoring the `fs` crate's
streaming interfaces.
## Changes
- `crates/worktree`:
- Add dependencies: `encoding_rs`, `chardetng`.
- Update `load_file` to detect encoding and decode content.
- Update `write_file` to handle re-encoding on save.
- `crates/language`: Add `encoding` field and accessors to `Buffer`.
- `crates/project`: Pass encoding information between Worktree and
Buffer.
- `crates/vim`: Update `:w` command to use the new `write_file`
signature.
## Verification
I validated this manually using a Rust script to generate test files
with various encodings.
**Results:**
* ✅ **Success (Opened & Saved correctly):**
* **Japanese:** `Shift-JIS` (CP932), `EUC-JP`, `ISO-2022-JP`
* **Chinese:** `Big5` (Traditional), `GBK/GB2312` (Simplified)
* **Western/Unicode:** `Windows-1252` (CP1252), `UTF-16LE`, `UTF-16BE`
* ⚠️ **limitations (Detection accuracy):**
* Some specific encodings like `KOI8-R` or generic `Latin1` (ISO-8859-1)
may partially display replacement characters (`?`) depending on the file
content length. This is a known limitation of the heuristic detection
library (`chardetng`) rather than the saving logic.
Release Notes:
- Added support for opening and saving files with legacy encodings
(Shift-JIS, Big5, etc.)

Closes #ISSUE
Problem:
- The status bar’s pending keystroke indicator (shown next to --NORMAL--
in Vim mode) didn’t clear when focus moved to another context, e.g.
hitting g in the editor then clicking the Git panel. The keymap state
correctly canceled the prefix, but observers that render the indicator
never received a “pending input changed” notification, so the UI kept
showing stale prefixes until a new keystroke occurred.
Fix:
- The change introduces a `pending_input_changed_queued` flag and a new
helper `notify_pending_input_if_needed` which will flushes the queued
notification as soon as we have an App context. The
`pending_input_changed` now resets the flag after notifying subscribers.

Some refactoring I ran into while working on automatic Markdown list
continuation on newline.
This PR:
- Moves `comment_delimiter` and `documentation_delimiter` computation
outside of newline method.
- Adds `NewlineFormatting`, which holds info about how newlines affect
indentation and other formatting we need.
- Moves newline-specific methods into the new `NewlineFormatting`
struct.
Release Notes:
- N/A
Fixes an issue where we would update the imports after a file rename in
TypeScript, but those changes wouldn't surface anywhere until those
buffers were manually opened
(https://github.com/zed-industries/zed/issues/35930#issuecomment-3366852945).
In https://github.com/zed-industries/zed/pull/36681 we already added
support for opening a multibuffer with edits, but vtsls has a different
flow for renames.
Release Notes:
- Files with updated imports now open in a multibuffer when renaming or
moving TypeScript or JavaScript files
Closes#43722
Release Notes:
- Fixed an issue where auto-indentation didn’t work correctly for Python
code blocks in Markdown.

Fixes the hang introduced in #44995 (which was reverted in #45011) and
re-enables the optimization.
## Background
PR #44995 introduced an optimization to skip rendering lines that are
clipped by parent containers (e.g., when a large AutoHeight editor is
inside a scrollable List). This significantly improved performance for
large diffs in the Agent Panel.
However, #45011 reverted this change because it caused the main thread
to hang for 100+ seconds in certain scenarios, requiring a force quit to
recover.
## Root Cause
The original analysis in #45011 suggested that visible_bounds wasn’t
being intersected properly, but that was incorrect—the intersection via
with_content_mask works correctly. The actual bug: when an editor is
positioned above the visible viewport (e.g., scrolled past in a List),
the clipping calculation produces a start_row that exceeds max_row:
1. Editor’s bounds.origin.y becomes very negative (e.g., -10000px)
2. After intersection, visible_bounds.origin.y is at the viewport top
(e.g., 0)
3. clipped_top_in_lines = (0 - (-10000)) / line_height = huge number
4. start_row = huge number, but end_row is clamped to max_row
5. This creates an invalid range where start_row > end_row
This caused two different failures depending on build mode:
- Debug mode: Panic from subtraction overflow in
Range<DisplayRow>::len()
- Release mode: Integer wraparound causing blocks_in_range to enter an
infinite loop (the 100+ second hang)
## Fix
Simply clamp start_row to max_row, ensuring the row range is always
valid:
```rs
let start_row = cmp::min(
DisplayRow((scroll_position.y + clipped_top_in_lines).floor() as u32),
max_row,
);
```
## Testing
Added a regression test that draws an editor at y=-10000 to simulate an
editor that’s been scrolled past in a List. This would panic in debug
mode (and hang in release mode) before the fix.
Release Notes:
- Improved agent panel performance when rendering large diffs.
Follow-up of https://github.com/zed-industries/zed/pull/44887
This fixes remote server builds.
Additionally:
* slightly rewords workspace trust text in the security modal
* eagerly ask for worktree trust on open
